Degradation Compounds

Degradation compounds in cannabis refer to aromatic molecules formed when cannabinoids, terpenes, and other plant compounds break down through heat, light, oxidation, or microbial activity. These secondary metabolites include aldehydes, ketones, alcohols, and organic acids that emerge during drying, curing, storage, or combustion. While the original plant contains primarily fresh terpenes and cannabinoids, storage conditions and processing methods significantly alter the aromatic profile over time. Understanding degradation helps breeders and cultivators predict how volatile compounds will shift during the post-harvest window. This knowledge is particularly relevant for seed preservation, clone stability, and consistency in commercial breeding programs.

Breeders working on shelf-stability and storage longevity often select for chemotypes that degrade predictably or maintain aromatic integrity longer. Knowledge of degradation pathways informs preservation protocols—such as controlled atmosphere storage, humidity management, and packaging selection—ensuring genetic material remains viable and true-to-type across multiple generations.
